Abstract

1,185,404. Friction welding. CATERPILLAR TRACTOR CO. 16 June, 1967 [30 June, 1966], No. 27973/67. Heading B3R. An inertial welding machine comprises a non- rotatable chuck 13 for holding one part to be welded WP1, and a chuck 14 for holding a second part WP2, chuck 14 being rotated by a motor 19 through an hydraulic coupling 21, a belt drive 22, an hydraulic clutch 23, a planetary drive 24 and a load cylinder assembly 17. Inertial weights 18, for storing the welding energy are mounted on the chuck spindle 16. Cylinder assembly 17 comprises a hollow hydraulic piston 28 for moving the part WP2 into engagement with part WP1, a shaft 26 splined to drive 24 at 66, and to spindle 16 at 72, and an hydraulic piston 62 fixed to shaft 26, for moving the latter axially, so as to actuate the chuck 14. In operation, parts to be welded are clamped in chucks 13, 14, and clutch 23 is engaged. Motor 19 accelerates spindle 16 to a preselected speed, and the clutch is disengaged. Pressure fluid is supplied to piston 28, so that the parts WP1, WP2 are engaged, and when the energy stored in weight 18 is expanded, the welding process is completed. Piston 62 is supplied with pressure fluid, and drive shaft is moved axially to unclamp the jaws of chuck 14 so as to release the workpiece.
